This wasn't addressed to me but I can't resist answering.
You simply want to trade government corruption for business corruption.
Absolutely. Businesses don't have a monopoly on the legal use of force or the power to tax. A corrupt government is infinitely more dangerous than a corrupt business.
The difference being that we can vote our corrupt government officials out of office.
That presumes you can remove the incentives that corrupt from politics, otherwise you're just voting in new people to be corrupted. Libertarians generally believe that the bad rise to the top, but that's a push and a pull effect, where the nature of power, as Lord Acton said, "tends to corrupt". So you have the worst people seeking power, and power corrupting the less than worse people along the way. A system of so much power has all of the wrong incentives for justice, honesty, transparency and accountability.
Market firms on the other hand have to answer to profit and loss. They can't vote themselves more money if they fuck up.
In the market, you can bankrupt a bad company by refusing to give them your business. It's the equivalent of voting out the bums, but the difference is, you aren't restricted to one sort of replacement in one single system. You have choices when you cut the cord.
I think the free market is a great idea, but with zero regulation it wouldn't remain free for long.
If it is regulated, then it isn't free.
I am not being patronizing with this, I really am trying to make a convincing argument.
If we work from a basic logical principle, the law of identity, which is basically, A = A. In other words, A cannot be equal to not A.
Using the law of identity, if a free market is when there is no regulation, then the only way it can become unfree is if it is regulated.
A regulated market is not a free market, and regulation isn't a result of market failure, but the actual cause of market failure.
The real confusion I think stems from the idea that the market has to yield perfect outcomes (like expecting private businesses to maintain universal free speech regardless of cost) and that since we know it can't, then the government has to step in to force perfection on the market. An outcome which we also know, does not happen with government intervention.
The question really is, the state or the market. Both can lead to less than desirable outcomes, but if one really believes in individual freedom, then it seems to me that the market is the only process consistent with that goal.
And if one was predisposed to get empirical (claims to reality as opposed to theory), there is massive evidence that free markets create economic prosperity and social harmony, and increases in regulation diminishes prosperity and institutionalizes antisocial behavior commensurately.
